i've so far wasted over a two weeks, across multiple days of reading, attempts, restore to stock, different combos of recoveries, to get lg v20 h918 working properly, with issues or shortcomings no matter what i try, really need official stock to los tested directions.
i was almost going to just go with LOS P unofficial to keep encrypted data twrp access instead of having to disable SELinux in LOS Q with Permissiver_v5.zip (suggested and seems to fix many things not working right, like disappearing camera, auto rotate sensors not working, clock resets, but then camera is crashing again)...
but the ir crashes after first use in both P and Q on my H918 device, so on top of losing fm radio... about the only benefit over my current s5 is going from 2g to 4g ram, since that has a consistently working ir under LOS P.
i'm so over the current state of android mobile technology, maybe i should just look for a replacement s5 since my screen is dying... or just use this v20 in stock O with Magisk mode.
